SOLE-EDGE SETTER.

Specification of Letters Patent.

Patented Sept. 10, 1918.

Application filed June 1, 1918. Serial No. 237,772.

To all whom it may concern:

Be it known that I, OTIS R. ANGELL, a citizen of the United States, residing at Bradford, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in S0leEdge Setters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in machines employed for setting or burnishing the edges of shoe soles, and one object is to provide a machine of this class in which the burnishing tools have movement in one plane only, rather than traveling on an are as heretofore.

A further object of the invention is to provide a pair of burnishing tools for use on different parts of the sole, and to make provision whereby either of-said tools may be brought into play while the machine is in operation.

With the foregoing objects in view, the invention resides in the novel features of construction and unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which form a part of this application and in which:

Figure l is a side elevation of the machine partly in section; a

Fig. 2 is a vertical transverse section of the plane of the line 2-2 of Fig. 1;

Fig. 3 is a detail front elevation of the tool carrying head and associated parts;

Fig. 4 is a detail horizontal section on the line 4-4 of Fig. 1; and

Fig. 5 is a side elevation of one of the bearing carrying plates.

In the drawings above briefly described, the numeral 1 designates the vertical standard of a sole edge setting machine, the upper end of said standard having a hollow head 2 provided at one end with a substantially rectangular casing 3 whose outer end is closed by a removable plate 4, said plate having an opening 5 through which a downwardly curved arm 6 projects to carry the burnishing tools. The inner end of arm 6 is joined to one side of a substantially rectangular block 7 mounted for horizontal reciprocation in the casing 3, the upper and lower edges of said block being shown provided with V- shaped grooves 8 which receive therein similarly shaped tracks 9, said tracks bearing against the top and bottom of the casing 3 and having vertically extending pins 10 near their ends received slidably in openings 11 formed in said top and bottom. The lower track 9 is secured rigidly against the bottom of the casing by a central screw 12, while a central adjusting screw 13 is provided for retaining the upper track 9 snugly in engagement with the sliding block 7, said set screw being provided with a suitable lock nut 14.

The side of block 7 opposite the arm 6, is provided with a preferably rectangular socket 15 having parallel vertical side walls 16, said socket receiving therein a second rectangular block 17 provided with vertical edges engaging the side walls 16 of said socket, said edges of the block 17 each having a vertically elongated recess 18. Rectangular plates 19 are snugly received in the recesses 18 and carry ball or other appropriate anti-friction bearings 20 which travel on the side walls 16 of socket 15.

Adjacent its center, the block 17 is provided with an opening 21 in which is positioned the ball bearing 22, said bearing receiving therein an eccentric wrist pin 23 on the end of a horizontal drive shaft 24 which is mounted rotatably in the head 2 and extends into the casing 3. By this arrangement, as shaft 24 rotates, the block 17 will reciprocate vertically in the socket 15 and the block 7 will be horizontally reciprocated to similarly move the tool carrying arm 6, particular emphasis being laid upon the fact that this arm moves back and forth on a straight line rather than on an arc.

Preferably employedin connection with the features so far described, is a metal disk 25 which is secured on the end of shaft 24 adjacent the inner sides of the two blocks 7 and 17. The lower end of the casing 3 is adapted to contain lubricating oil, and by providing the disk 25, this oil will be continually thrown over the moving parts of the device, thus insuring easy and approximately noiseless operation thereof. Furthermore, little vibration takes place in comparison to machines which have here tofore been used.

The-free end of arm 6 is provided with a vertical bearing 26 whose lower end is enlarged at 27 and provided with a transverse groove 28. A tool holding head 29,.ismovable bodily with the bearing 26 and is provided on its upperend with a transverse rib 30 received normally in the groove 28 to prevent rotation of the head. The burnishing tools 31 and 32 are detachably secured to the lower end of the head'29 by suitable spring detents 33 and byturning the head a half revolution, either of said tools may be brought into operative relation with the work restR which may be ofthe usual-or any preferred design.

Above the arm 6, the end plate 4 of, casing -3 is provided with an integral supporting arm 34 having in its outer end a socket 35 receiving a lateral stud36 on a substantially vertical bearing 37-which is alined with the bearing 26, a set screw 38 and groove 39 be ing provided to retainthestud 36in the '25 socket 35, and at'the same-time to permit rocking of said stud. A-fiexible shaft 40' is rotatably mounted in the two bearings 26 and 37 and is connected operatively with the head 29 for rotating the latter while the machine is in operation, to bring eithertool 31or 32 into play;- ln' the present embodi- 'ment of the invention, theshaft 40-i's-formed of a lower section 41 rotatable and sliidable .in-the bearing 26, an upper section 42 slidable and-rotatable in the bearing 37, and a connectionqbetween the two sections, the lower section 41 being joined to the'head 29, while the upper section is provided with an operating knob I 43. Suitable coiled springs 44 are provided for the two sections 41 and 42- to normally shift them-upwardlyso as to engage the rib 30 with-groove 28, to -hold the head 29 in adjusted position. By push- 7 'ing downwardly onthe head43 however and turningthe same, the locking; means 28-30 are-released and thehead rotated to bring the proper tool-into play. Release of the knob then permits the springs 44 to return the several parts to-normallocked position.

v The aforementioned connection between the twoshaft sections 41 and 42 mi-ght well be embodied in'a-number of forms, but I prefer to providesaid section-41 with a head 45 having a V-shaped socket 46in its upper I end receiving the similarly shaped lower end 47 of shaft section 42,.the oppositesides of said end-being flattened so that they may slide upoirthe sides ofathe socket -46 but may not. rotate in respect thereto. The socket 46 is of sufficient dimensions'to permit horizontal reciprocation :o'f vthe tool carrying'jhead 29 without continually oscillating the upper shaft section 42, andalthough this section -will berockedto and :fro whenisa'idheadis turned .a quarteriof a revolution,.thermove- :ingihaving openings adjacent r-the ends of .mount said. block @for horizontalimeciprocament will not be undesirable to theoperator, due to the fact. that the knob. 43.is.located in close proximity to the axis upon which the bearing 37 rocks, themovement of said knob being therefore slight.

.From the foregoing, taken in connection with the accompanying drawings, it will be obvious that although I have provided a comparatively simple sole edge setting machine, the same will be highly efficient and in every way desirable, particular emphasis being laid upon the noveloperating' means -making such minor changes as occasion may dictate.

I claim: 1. A soleedge burnisher comprising :a block mounted for horizontal reciprocation and having in one side-a=socket withuparvallel vertical. sideiwalls, anarm extending from the other. side ofsaid: block and :carrying burn-ishing tool, a secondand Zvertically reciprocating block received in said socket and having two .vertical t-edges teach provided with a vertically elongated recess, a pair- .of verticalv plates ;disposed ..-rsnugly in said recesses carrying anti-friction bearings contacting with said side walls of the socket, said second 3 block having nan. opening, and a: drive shaft having anweccentric wristipin mounted insaid opening.
